Benefits of technology

[0018]The aim of the present invention is to produce an insulating glazed element formed from at least two glass sheets and at least one section, which makes it possible to prevent the appearance of condensation and the formation of frost on the periphery.

Problems solved by technology

With chest freezers, and in spite of the use of insulated glazing, there is still the problem of condensation or of frost at the periphery of the glazed surface.
The presence of condensation water or of frost has drawbacks: reduction in the field of vision through the glazed element, appearance of mold, formation of puddles on the ground, transfer of moisture to the skin, the presence of stains on the clothing, the risk of the skin “sticking” to the frosted parts, etc.
However, this bead is not entirely satisfactory:it is minimally adjustable because its length depends entirely on the dimension of the glazing,it is tricky and expensive to implement because it is necessary to make a perfectly gaged groove in the thickness of the seal of the glass sheets,since the contact area between the bead and the frame is small, the heating efficiency is low, andgiven that it is fed by an electric current of high voltage (about 220 volts), a safety device, which breaks the circuit in the case of accidental breakage of the glass, must absolutely be combined therewith.

first embodiment

[0047]FIG. 2 shows a front view of a glazed element according to the invention.

[0048]FIG. 3 is a vertical section through this same element.

[0049]According to this embodiment, the glazed element comprises two glass sheets 11, 12, provided with a heating border 18, supported by a frame having the shape of the section 13. In FIG. 2, the section 13 is represented by dotted lines in order to show the heating border 18 more clearly.

[0050]The glass sheets 11, 12 are separated from each other by a space 14 and joined at the periphery by a seal 15, which is watertight. Into the space 14, at a small distance from the edge of the sheets 11, 12, is inserted a hollow section 16 containing a desiccating agent, which is fixed to the glass by an adhesive bead 17. The outer sheet 11 is provided, on its external face, with a heating border 18 of variable width which extends over the four sides of the sheet, the ends of which bear a terminal 19 for the electrical supply. A heat-conducting seal 20 pro...

second embodiment

[0051]FIG. 4 shows a front view of a glazed element according to the invention and FIG. 5 is a vertical cross section through this element.

[0052]As above, the element consists of glass sheets 11, 12 supported by the section 13, also shown in dotted lines in FIG. 4. The glass sheets 11, 12, separated by the space 14, are joined at the periphery by the seal 15. The space 14 comprises the hollow section 16 containing the desiccating agent and the adhesive bead 17 (not shown). In this case, the outer sheet 11 bears, on the internal face, two different heating borders 21, 22, of the same width and of a length substantially equal to the sides of the sheet 11, the ends of which bear terminals 19. Intermediate elements 23 are attached to the borders 21, 22 by adhesive bonding or by welding at the end 24, the end remaining free 25 itself being folded toward the sheet 11 and lying in a plane substantially parallel to the thickness of the sheet. The entire surface of the end 25 is thus exposed...

third embodiment

[0053]FIG. 6 shows a front view of a glazed element according to the invention and FIG. 7 is a vertical section through this element.

[0054]In this case, the elements consist of three sheets of glass 11, 12, 26 supported by the section 13, also shown in dotted lines in FIG. 6. The glass sheets 11, 12, 26, separated by the spaces 14, 27, are joined at the periphery by the seal 15. Each space 14, 27 contains the hollow section 16 containing the desiccating agent and the adhesive bead 17 (not shown). In this case, the intermediate sheet 12 bears, on the external face, a heating border 28, formed from upper 29 and lower 30 strips connected together at one side, whose ends provided with terminals 19 are located on the side of the sheet away from the previous side.

[0055]In this case, the intermediate element 31 is a T-section, whose web 32 is fastened to the strip 29 of the heating border 28 and whose flanges 33 lie in a plane substantially perpendicular to the plane of the sheet 26 bearin...

Abstract

An insulating glazed element including at least two glass sheets, separated from each other by a space and joined at their periphery by a seal, and at least one section. The glazed element has at least one heating border on at least one face of at least one glass sheet, and the border is covered by the section and joined to the section by a heat-conducting seal.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]2. Discussion of the Background[0003]The invention relates to an insulating glazed element comprising at least two glass sheets separated from each other by a space and at least one support element, especially for a refrigerated enclosure.[0004]Glazing panels are generally placed in a frame making it possible to support them for the purpose of their use in fields where their thermal insulation properties are sought (building, refrigeration, etc.).[0005]It is well known that when a cold wall is in contact with hot and moist air, the wall becomes covered with water from the condensation of the ambient water vapor, it being possible for this water even to become transformed into frost if the temperature is low enough. More specifically, it is when the temperature of the wall is less than the dew point of the ambient air that condensation is produced. In the case of glazing panels, the condensation may appear on the glass a...
